The air conditioning in my cadillac doesn't blow out of the vents on the dash. But it blows air out of the side vents on the doors. How do I use the self diagnostics feature on my air conditioner?
A few different items can cause the air to not blow out of the dash vents. The most common are a blend door or a control switch. The best method for the AC diagnosis feature can be found in the vehicles owners manual. I recommend having your AC checked by a qualified technician, such as one from YourMechanic, to have the problem diagnosed and repaired correctly.
